Memory slots have to be page aligned to get entered into KVM. There is existing logic that tries to ensure that we pad memory slots that are not page aligned to the biggest region that would still fit in the alignment requirements. Unfortunately, that logic is broken. It tries to calculate the start offset based on the region size. Fix up the logic to do the thing it was intended to do and document it properly in the comment above it. With this patch applied, I can successfully run an e500 guest with more than 3GB RAM (at which point RAM starts overlapping subpage memory regions).
